If you phone scamp rather than order from the online store the shipping goes way down. They ship USPS and it costs about 1/2 or less of what FedEx does if ordered through the online store. Fasteners and smaller items it is especially pronounced price difference.
Not 100% complete but covers a lot of the sizes.

I would call your attention to post #5 where Carol starts a discussion on an easy way to cut a rivet to length. That one has saved my bacon a couple of times.

There was also an issue with the acorn nuts, my older model used a smaller nut, a size not commonly available, I was able to use a common size and drill about 1/2 the threads out and it then fit the rivets fine. Notes on that are second page of the thread.
Someplace there is a thread on doing
windows that rivet in, process to get good seal. Cross tighten and only tighten a bit, then let the butyl tape "adjust" to the pressure and come back later to tighten some more, until the rivet pops.
